Using Isotopes

The video tutorial explains the concept of isotopes, which are variants of elements with the same number of protons and electrons but different numbers of neutrons. It highlights the significance of isotopes in scientific research, particularly in isotopic labeling for tracking chemical reactions. The tutorial also delves into the medical applications of isotopes, using the example of radioactive iodine to diagnose thyroid issues. Overall, the video emphasizes the critical role isotopes play in both laboratory and medical settings.

What distinguishes isotopes of the same element from each other?

• Different number of protons

• Different chemical properties

• Different number of electrons

• Different number of neutrons

Why are isotopes particularly useful in isotopic labeling?

• They have different chemical properties

• They can be easily detected due to their unique neutron count

• They are more reactive than other elements

• They are cheaper to produce

In what field do isotopes show the most promise according to the video?

• Astronomy

• Agriculture

• Medical field

• Environmental science

How can radioactive iodine help in diagnosing thyroid issues?

• By changing the color of the thyroid

• By being absorbed by the thyroid and emitting light

• By tracking its movement to identify problem areas

• By increasing the size of the thyroid

What is the primary benefit of using isotopes in medical experiments?

• They are less expensive than other methods

• They can be used to track specific molecules in the body

• They improve the taste of medicines

• They are more stable than other elements
